Specification of Letters Patent.

Patented Nov. 16, 1909.

Application led September 23, 1908. Serial No. 454,334.

To all whom it may concern:

Be it known that Vieron Gonnrix, a subject of the King of Great Britain,residing at the city and district of Montreal, in the Province ofQuebec, Canada, have invented certain new and useful Improvements inh'iailing-'lubesg and do hereby declare that the following is a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

The invention to be hereinafter described relates to mailing tubes, andmore particularlyT to a mailing tube which may be shipped fiat in bulkand rolled to various diameters.

As heretofore made, mailing tubes have been manufactured locally only.It has not been possible to ship them to any considerable distances fromthe points where they are turned out, because their bulk necessitates avery high, and practically prohibitive, freight charge. This is due tothe fact that the tubes are manufactured and must be shipped as tubes.Besides this great disadvantage, the tubes as now made are of fixeddiameters, which cannot be varied to adapt them for different sizes ofrolls. Also, the tubes as now constructed have no adequate means forpreventing` removal of packages through their ends. lt is with an ideato avoid these and other objections, that the present tube has beendevised.

In order to more clearly disclose the construction, application and useof the invention, reference should be had to the accompanying drawingsforming part of the present application.

Throughout the several views of the drawings, like reference charactersdesignate the same parts.

In the drawings: Figure 1 is an inside perspective view of the tube inunrolled position; and, Fig. 2 is a detail longitudinal section throughthe gripping member.

Broadly speaking, the tube comprises a flexible sheet of material, suchas card-board, leather-board, or the like, adapted to be rolled intotube form, a wrapping sheetattached thereto and provided with a gummededge by which the tube may be sealed, and a plate or strip adapted to besecured to the inner face of the flexible sheet and provided withgripping teeth adapted to engage and hold an article within the tube.

ln manufacturing the tube, a flat, flexible sheet l of any suitablematerial, such as cardboard, leather-board, or the like, may be used asa foundation. To one longitudinal edge of this foundation is secured, bypasting or otherwise, an edge of the wrapping sheet 2. The oppositeinner edge of this wrapping sheet is gunnned, as at 3, so that it may bestuck to the outer face of the roll when the tube has been formed. Thesheet 2, should, of course, be somewhat longer than the foundationsheet, and somewhat wider, so that it may be turned in at the open endsof the tube and may extend across the edges of the tube when folded.

In order to prevent removal of the contents of the tube, a grippingplate t has been provided. This comprises a simple strip having its twoends turned down so that they may be passed through the approximatecenter of the foundation sheet and clenched to hold it in position. Theplate 4t is provided with sharp projecting points or teeth 5, adapted toengage the article within the tube and securely hold it againstwithdrawal, as will be readily understood.

ln shipping this tube, the foundation and wrapping sheets may beassembled and laid out flat so that they may be handled in 'mass just aspaper sheets. In such case, the gripping plates will be shippedseparately in quantity. Or, if desired, the gripping plates may besecured to the foundation sheets and the teeth 5 pressed flat, thusallowing shipment of the complete device in very large quantities andready for immediate use.

It will be 'seen that a mailing tube is provided which may bemanufactured very cheaply and shipped in great quantities with a minimumfreight charge, thus allowing the tubes to be made at one or two pointsonly instead of at a great number of different places. Furthermore, atube of this character is adaptable to a wide range of diameters, willinclose the article tightly, and will absolutely prevent withdrawal ofthe article from the tube. Also in tubes of this character the inclosedarticle may be readily and rapidly removed without injury by simplycutting the wrapping sheet along the longitudinal line of closure of thetube.

It is thought that the use and application of the tube will be readilyunderstood from the preceding detailed description.

Changes may be made in the construction, arrangement and relativedisposition of the several parts, without in any way departing withdownturned ends by which it may bel from the field and scope of thesame, and it secured to the foundation sheet, and having is meant toinclude all such within this apgripping teeth projecting inwardly fromits plication, wherein only a preferred form has face. 1.5
